Interesting Intake option

First intake on the page.

It looks like it would bolt to the engine. If you look at the measurements, it won't clear the hood by about 1", and that's not counting the engine moving around. However, if you used a hoodscoop that was big enough it should fit. Maybe a shaker? Or a cowl?

Well there is work being done with bolting up LS6 Intakes so far as it bolting up in not to worried. More of the hood clearance issue. But think a LS6 intake should get us 15hp better. Thats just a quess as that is what alot of F body guys saw when they swapped there LS1 intakes for LS6 ones. And that website clamed another what 20hp. Of course that was with some other work to the motor. But this intake solves alot of the issues of installing a LS6 manifold into our cars, from the look of it. Would have to buy and try it of course. Some of the problems of swapping intakes making room for the Opening in the intake track because we have an oil presure sensor built into the top Valley section of the motor off the DOD which is causing the restriction of our intakes in the first place. THen u have to modify the connector for the DOD. SO if this opened up room like it looks like it would. that would eliminate alot of the work modifiing . Then just get a nice big cowl/Shaker hood for clearance. Maybe even the Inferno Hood might clear it dont know though. As i have never seen one in person.

hey panther...i was looking at the clearance on the hood...the inferno probobly wouldnt do due to the hood inlets are so far up toward the nose.....and the hood has a flat design underneath like the OEM hood...the only protion that is different on the underside of the hood as far as the inferno goes, is the port in front underneath the dual inlets....there is a pic as well of the underneath on PFYC website in the inferno pictures in that section you will see what i mean...there isnt much more vertical clearance over the manifold with this hood either...just from what i observed...

Ya i was looking at it too. just have to modify the hood now lol. I want this intake. i think it will be awsome. Just like anything solves one problem creates another. Most ls6 intakes are be sold for somewhere between 300-350 plus shipping. SO if u can buy this for 400, thats a good deal. Plus then the down time for removing your DOD plate and modifing it. Youcan drive a car around with out a hood, harder to do with out a major part of the oil system.

Wouldn't you have to make mods to the fuel rails for this intake mainfold? It sounds very interesting, but I feel there is a lot of mds that have to be performed here.

[Panther427]

Yes most likely. The LS4 intake set up is just a pain no matter how u look at it. To swap intakes you will have to be modding something. Weather it be sensor locations, mod the oil preasure sensor, extend electrical wire harness, or fuel rails there just isn't an easy swap. However there is intake manifold and throttle body porting avalible to us.

Who and where is the Intake and TB mod (porting) for us? Need more info. It will help me determine what cam I'll be going with this Fall/Winter when I'll do most of my major MOD.

[Panther427]

Fasterproms out of florida. You will have to do more tinkering with you HP tunner as u have to make adjustments to prevent a code and take full use of the mod. On a side note cams are very tricky. If u get one that moves the power band you will be hurting your self as you will be out of it when the car shifts.

[Beamie]

Comp Cams make very broad powerband Cams. I'm pretty sure with our engine setup, as it is, that intake porting or intake replacement will be necessary to take advantage of one of their cams that I'm looking at. Where I see their powerband starting at, gearing or even a torque converter change might not be necessary for the street, but serious drag racing would definitely benefit from making that mod too.

From what I have experienced thus far, making performance engine upgrades isn't too difficult as long as it isn't too radical and you direct it for a particular purpose. I don't believe in over porting for a street vehicle because you want to maintain good air velocity throughout the powerband. After that, we can make adjustments to the computer to put everything else into perspective. Remember, most of us drive according to our tach and it usually hovers in and around 2000-2200 RPM's.

My quandary is that Hogan 3" DP. Why add that if we haven't modified our crossover pipe? Shouldn't that be at least a 1/2" larger? Larger pipes, from my experience, hurts low end torque because air velocity slows considerably at lower RPM's. For our engine size and those of us who plan on keeping our vehicles a daily driver, any pipe over 2.5" would be good for a track piece and any engine that's going to see a lot of high RPM's and push closer to that 7 grand mark and higher. I drive my car with my grandkids in the back seat. We go for Quick rides through the park and go get ice cream.

Making good power to 6 grand is my intent and purpose. How fast I want to get it there, well....? Let's say, I'll worry about those other changes I mention earlier if and when I feel I'm not getting there fast enough and I want to get there a little quicker. Remember, I still want to drive this thing on the highway, like to Boston, at least on a tank and a half of gas. I can do it now on one tank. 13.93 in the 1/4 is what we be running, now, at ATCO Raceway. Low 13's is where we wanta be at. Remember, it still my family's sedan. Just a little faster then normal.
